java - 请放心 json-schema-validator

Question

我正在使用放心的 json 模式 validator ，这是我的架构:

{
  "$schema": "http://json-schema.org/draft-04/schema#",
  "id": "http://jsonschema.net#",
  "type": "object",
  "required": false,
  "properties": {
    "id": {
      "id": "http://jsonschema.net/id#",
      "type": "object",
      "required": false,
      "properties": {
        "keyVal": {
          "id": "http://jsonschema.net/id/keyVal#",
          "type": "string",
          "required": false
        }
      }
    },
    "name": {
      "id": "http://jsonschema.net/name#",
      "type": "string",
      "required": false
    },
    "description": {
      "id": "http://jsonschema.net/description#",
      "type": "string",
      "required": false
    },
    "updatedBy": {
      "id": "http://jsonschema.net/updatedBy#",
      "type": "string",
      "required": false
    },
    "dateModified": {
      "id": "http://jsonschema.net/dateModified#",
      "type": "integer",
      "required": false
    },
    "arePhrasesCaseSensitive": {
      "id": "http://jsonschema.net/arePhrasesCaseSensitive#",
      "type": "boolean",
      "required": false
    },
    "phrasesList": {
      "id": "http://jsonschema.net/phrasesList#",
      "type": "array",
      "required": false,
      "items": [
        {
          "id": "http://jsonschema.net/phrasesList/0#",
          "type": "object",
          "required": false,
          "properties": {
            "value": {
              "id": "http://jsonschema.net/phrasesList/0/value#",
              "type": "string",
              "required": false
            },
            "weight": {
              "id": "http://jsonschema.net/phrasesList/0/weight#",
              "type": "string",
              "required": false
            }
          }
        },
        {
          "id": "http://jsonschema.net/phrasesList/1#",
          "type": "object",
          "required": false,
          "properties": {
            "value": {
              "id": "http://jsonschema.net/phrasesList/1/value#",
              "type": "string",
              "required": false
            },
            "weight": {
              "id": "http://jsonschema.net/phrasesList/1/weight#",
              "type": "string",
              "required": false
            }
          }
        },
        {
          "id": "http://jsonschema.net/phrasesList/2#",
          "type": "object",
          "required": false,
          "properties": {
            "value": {
              "id": "http://jsonschema.net/phrasesList/2/value#",
              "type": "string",
              "required": false
            },
            "weight": {
              "id": "http://jsonschema.net/phrasesList/2/weight#",
              "type": "string",
              "required": false
            }
          }
        }
      ]
    }
  }
}

这是我的 JSON:

{
"id": {
"keyVal": "jkl3"
},
"name": "name",
"description": "description",
"type": "TYPE",
"updatedBy": "updatedBy",
"dateModified": 1398845197348,
"arePhrasesCaseSensitive": false
}

我正在使用 juint 来使用断言进行测试:

json = SimpleFileReader.getFileAsString("my.json");

assertThat(json, matchesJsonSchemaInClasspath("products-schema.json"));

我的 json-schema-validator 版本是:2.3.1

<dependency>
    <groupId>com.jayway.restassured</groupId>
    <artifactId>json-schema-validator</artifactId>
    <version>2.3.1</version>
</dependency>

我错过了什么？

(此处为 json-schema-validator 部分的作者)您的架构确实无效。 "required" 关键字根本不是这样使用的。

不幸的是，您没有与架构关联的错误消息，您可以尝试粘贴它 here查看错误。

您尝试使用 required ，因为它基本上是在 v3 草案中定义的，而您的“顶级”required 无论如何都是没有意义的。您想要的是将其作为架构:

{
  "$schema": "http://json-schema.org/draft-04/schema#",
  "id": "http://jsonschema.net#",
  "type": "object",
  "properties": {
    "id": {
      "id": "http://jsonschema.net/id#",
      "type": "object",
      "properties": {
        "keyVal": {
          "id": "http://jsonschema.net/id/keyVal#",
          "type": "string"
        }
      }
    },
    "name": {
      "id": "http://jsonschema.net/name#",
      "type": "string"
    },
    "description": {
      "id": "http://jsonschema.net/description#",
      "type": "string"
    },
    "updatedBy": {
      "id": "http://jsonschema.net/updatedBy#",
      "type": "string"
    },
    "dateModified": {
      "id": "http://jsonschema.net/dateModified#",
      "type": "integer"
    },
    "arePhrasesCaseSensitive": {
      "id": "http://jsonschema.net/arePhrasesCaseSensitive#",
      "type": "boolean"
    },
    "phrasesList": {
      "id": "http://jsonschema.net/phrasesList#",
      "type": "array",
      "items": [
        {
          "id": "http://jsonschema.net/phrasesList/0#",
          "type": "object"
          "properties": {
            "value": {
              "id": "http://jsonschema.net/phrasesList/0/value#",
              "type": "string"
            },
            "weight": {
              "id": "http://jsonschema.net/phrasesList/0/weight#",
              "type": "string"
            }
          }
        },
        {
          "id": "http://jsonschema.net/phrasesList/1#",
          "type": "object"
          "properties": {
            "value": {
              "id": "http://jsonschema.net/phrasesList/1/value#",
              "type": "string"
            },
            "weight": {
              "id": "http://jsonschema.net/phrasesList/1/weight#",
              "type": "string"
            }
          }
        },
        {
          "id": "http://jsonschema.net/phrasesList/2#",
          "type": "object"
          "properties": {
            "value": {
              "id": "http://jsonschema.net/phrasesList/2/value#",
              "type": "string"
            },
            "weight": {
              "id": "http://jsonschema.net/phrasesList/2/weight#",
              "type": "string"
            }
          }
        }
      ]
    }
  }
}

基本上，您的架构不再有任何“必需”。请注意，默认情况下，对象成员不需要存在；仅当它们存在于数据中时才会被验证。

如果您希望成员“foo”和“bar”出现在 JSON 对象中，那么您可以这样写:

{
    "type": "object",
    "required": [ "foo", "bar" ],
    "etc": "etc"
}
